301* PENNSYLVANIA. j e a fijeiljxsswms HEATING AND FINISHING [Iv Ac -uN have "invented eertain'new and useful Improvementsin'Glassware Heating and Fin ishing jMachines,for which the following is a specification.

My invention relates to the art of fire-polishing, heating, and finishing glassware such as lamp-chimneys, bottles, &c.and particularly tomaclunes for performing all the operations of finishing automatically I andat-the same timel' Its primary objects 'ane toautomfaticallyand continuously heat uniformlya serie's'of articles in a particular place and heat'them gradually, so as to attain just the right temperature for finishing, to simultaneously carr on the heating with the finishing operations, such as crimping the ends of'lamp chimneys or forming bottleheads, &c., to provide an automatic finishing-machine, to provide a'series of improved sectional furnaces for these purposes, to provide means for operating a crimping-machine, andto generally improve the facility and efficiency of the handling of glass articles in finishing. These objects and other adattained by thedevices illustrated as applied toforming lamp-chimneys in the accompany'ing'd'rawin'gs' Figure 1 is a plan view of the whole apparatus, and" Fig; 2 "is a front elevation of the same. Fig. 3 is anend elevation and partial vertical section on the'line'3 in Fig. 1 looking in the direction of the arrow. Fig. 4 is a vertical section of one of the compartments of the furnace, taken on the line 4 in Fig. 1 and showingthe heating-burner for oil or gas.

For illustration I have shown a machine designed to heat andfire-polish and at the same time crimp the ends of lamp-chimneys;

ltwiil be understood that the chimney when made has the small end cut with a sharp edge, which makes it necessary to smooth it, either by grinding or by the process known as fire-polishing. The chimney also has to be heated gradually up to a soft state, and

then it is operated upon by a crimping-tool to form the weltlmown pearl'top or bead edge. These e eratiemg have heretofore been performed separately and in machines Specification of Letters Patent.

Application fiied August 6, 1906. Serial No. 329,272.

which were not automatic unless for the firepolishing. It has also been customary after 5 5 the fire-polishing to again heat the chimney by another operation for the purpose of crimping the ends, the chimney'being handied manually and being carried on a snap, removed and placed in a constantly-revolv- 6o ing crimping-machine. This all results in great expense and waste of time, as well as ad'- ditional danger of breakage by reason, of the increased handling and the second heating, while'uniformity of roduct was dependent entirely upon the ski l of the individual operator. My machine avoids these difliculties and cheapens the manufacture in general.

It will be seen from Figs. 1 and 4 thatI have provided a continuous series of furnace- 7o compartments 5, which are generally six in number and are formed, as shown in Fig. 4, with a slotted opening 5? at the upper and outer corner, so that the flame provided by the gas or oil burner6 is directed upwardly against the lamp-chimney 7 when carried over slot 5 as shown. These furnace-comcially adapted to this work and is one of the elements of my invention.

The burner may be of any desired form, the invention not being limited to any method of heating; but the device shown is well adapted to the purposes; It consists of an air-pipe 6 and a jet-pipe 6 forintroduc 95 tion of gas or' of oil in a vaporized state.

In front of the furnace-compartments 5 and mounted adjustably in position relative to the furnace is a frame'consisting of up rights 8 and a horizontal support 9, which [co may be of any desired form to support-and guide the continuous traveling chain 10, preferably driven upon sprockets 11 on the shaft 12, which in turn is driven by a band or cord on the sheaf 13. Some of the links 10 5 of the chain 10 are provided with upright posed to the different flames and in the.

supports 14, ending in forks 15-, whichmay carry the handle 16 of any convenient form of snap 17 for holding the lamp-chimney7 or other article being operated upon. In

order that the glass article may be uniformlydle 16 and having it engage an upwardly-' extended guide-flange 19 on the frame 9. By this means the snap,-with its chimney, being placed upon one of the pairs of forks 15 atthe left of the machine is carried gradually across the front of the furnaces and exmeanwhile is rapidly rotated in place, so that the end ofthe chimney is uniformly andgradually brought to the proper heat and preserved in shape. The flange 19 and the pulley 18 being of the grooveform, Fig. 3, insures the articles all being at the same distance from the flame and prevents their displacement in a lateral direction.

When'the article has been brought to the proper heat as it reaches the end of the furnace, as shown in Fig. 1, it comes opposite to the finishing-tool, which in this case is shown as a common crimper 20. This crimper is mounted upon a shaft 21-, which is carried in a movable frame 22 and is capable of shifting to and from the position of the chimney. Mounted upon the fixed support- 8 is a fixed rack 23, and on the shaft 21 is a pinion 24, which is normally out of an agement with the rack 23, as shown. from Fig. 3 it will be seen that the frame 22, carrying the crimper, slides upon-a fixed table 25 on the support 8 and is movable thereover in two'directions and guided by means of pins 26 and slots 27 in the fixedtable-plate- 25. The frame 8 carries a constantly-revolving wheel 28, which is driven by means of a cord 29 from a sheave on the shaft 12. This wheel has a cam 30, which at the proper time engages-themovable frame'22, as will be apparent from Fig. 3, and pushes said table over-'inthe direction of the arrow toward the carrier and-article. The first effect of this is to engage the pinion 24 with the rack 23 andat the same time engage the crimping-tool 20 with thelamp-chimney 7. At the same time the pins 26 move over in the slot 27 so that the carriage 22 may move forward, and a s ring-bolt 31, sliding. in a socket on the carriage 22, projects outwardly and engages a dog 32 on the traveling-carrier-chain 10. On the bolt, 31 is provided another pin 33, engaging slot 34 in the fixedplate 25. Now' action of the dog 32, engaging the pin 31, is to drag the carriage 22 forward in register with the moving glass article 7, and'atthesame time pinion 24 revolves the crimper and forms the ,end of the chimney or other article, as desired. When this operation is accomplished and the carriage 22 has moved forward the proper distance, the pins 26 first strike the mclined part of the cam-slot 27, which withdraws the carriage 22, removing the pinion 24 from mesh with the rack and relieving the crimp ing-tool from the article. At nearly the same time or shortly afterward the slot 34 draws the bolt 31 backward by means'of its pin'33,

'so as to disengage the dog 32 on the traveling. chain. At this point the carriage 22 is drawn back by a cord 35, which is operated by weight 36 or by a spring or any other convenient means. The carriage and crimpingtool thus return immediately in time to eat-ch the next chimney 7 and'repeat the operation just described.

, in order to allow for different lengths of glass articlesbeing used, the supports8 may be mounted .upon sliding ways 37 and be moved by screw-rodsBS, as shownin Fig. 3, so that the entire machine may be adjusted in position relative to the furnaces.

or snaps for the article is important, as it The feature ofremovability of the holders sometimes happens that an article is thicker or heavier than the average, and in such case it can be readily taken off handling it by the,

snap, and placed farther back on the carrier, so as to travel again through a heat zone. The adjustability of t e position art of the of the carrier toward. the furnace and the.

fact that the ware isalways in plain view of the operator are also important features where the articles sometimes vary in size or length. i

It will be understood that a large number of the rods 16, with the snaps 17, may be provided and adjusted to fit the articles, so that the articles are easily handled in putting on or taking off, and manifestly a returncarrier of any ordinary construction may be used for handling the snaps conveniently. The machine may thus be operated by two operators, one at one endto'place'the snaps with the articles in the forks 15 and'another at the far end to remove the finished chimney. It will be understood, of course, that. the same machine ma be used for any glass article requiring a finish made while it is in a plastic state.

The entire operation is automatic, and since every one of the articles goes through exactly the same manipulation the product will be thoroughly uniform, and there is no extra handling, so-that breakage is thus reduced to a minimum.

Of course the rods 16 ma be fixed in place as permanent parts of tie machine in the forks 15, and the snap 17 may be opened and the article 7 placed therein directly, so as to avoid the handling of the snaps themselves.
